. 1 Claim. 1

This application is a continuation-impartof my copending applicationSerial No. 490,266, filed June 10, 1943 now abandoned.

This invention relates to the arrangement of an implement upon a tractorfor ready removal from the tractor. More specifically, it relates tothe. arrangement of parts of a harvester-thresher mounted upon atractor.

Self-propelled devices such as harvesterthreshers are known, but in mostcases the propelling meansor tractor is inseparably connected to thedevice so that the tractor cannot be used for other purposes. In caseswhere a device such as a harvester-thresher is separably connected to atractor, the device is so arranged with respect to the tractor that. thetractor runs forwardly. This causes. the. mounting structure. for thedevice. upon thetractor to. be costly and com.- plicated. The presentinvention has tov do with the association of the device with. a tractorin such away that the tractor' runs backwardly for operation of. thedevice. This permits the mounting to be simplified. The presentapplication has to do with the arrangement of parts of aharvester-thresher with respect to one another so that detachment from.the. tractor is facilitatedo An object is to provide an. improvedtractor?- mounted implement Another object is the provision ofimprovements in a tractor-mounted device comprising crop-gathering meansand: crop-treating means.

A further object is to provide improvements in a tractor-mountedharvester-thresher.

Still another object is the provision of an improved. arrangement of.parts. of an. implement such as a harvester-thresher that will:facilitate detachment of the implement from the tractor.

Other objects will appear from the disclosure.

According. to the; present invention, a harvester-thresher composed of.a thresher and a harvester part is mounted upon. a tractor of thetricycle type in such: a way. that the thresher part extends: along the.tractor body within the. tractor wheelline with the rear'endof thethresher part adjacent the front end of the tractor body and the. frontend of the thresher part adjacent the tractor rear axle, and theharvester part is pivotally connected to the. thresher part adjacent therear'axle and extends downwardly and rearwardly to the rear of the rearaxle and laterally beyond one of the. tractor Wheels. For operation oftheharvesterthresher the tractor is run backwards. The.-harvester-thresher is detachably connected tothe. tractor so that it mabe removed therefrom, and the tractor may be used for other purposeswhile being run forwardly in the normal manner. Another significantfeature of the present invention is raising the harvester partsufiiciently so that, when the harvesterthresher is detached from thetractor and the tractor is moved away from the harvesterthresher, theharvester part will clear the tractor rear axle and wheels.

Figure 5' is a View similar to Figure 4 with a portion of both theharvester and thresher parts broken away to show the delivery ofmaterialfrom the harvester part tothe thresher part;

Figure. 6 is a View similar to Figure 3 showing a modified constructionin which the harvester part is moved outof interfering position withrespect to the tractor parts for removal ofthe implement from thetractor by separately disconnecting. and removing the harvester partReference character It designates a tractor having a narrow body I hanarrow steerable front rolling support I2; and a-transverse reardriveaxle structure. including. a. short right-hand rear axle 3; a wheel[4 connected thereto, an extended left-hand rear axle. l5, and a wheelit connected thereto. whereby the major portion of the weight of thetractor is carried on the wheel at the short axle sideof thetractor.Said tractor is adapted to operate in the reverse direction with; thedrive axle leading and the steerable support trailing. There is mountedupon the tractor at the extended axle side-an implement in the form of aharvester-thresher I? comprising essentially a thresher par-t l8 and aharvester part [9; The thresher part- I8 is supported-with itsstraw-discharging end. adjacent the normal.

front end. of. the tractor body H, this end of thethresher part beingthefrear end when the tractor: is' operated ini'reverse. direction, andits other and crop-receiving: end: on the left-hand.

rear axle 5 whereby the major portion of the harvester-thresher iscarried on the tractor at the extended axle side. The rear end of thethresher part l8 has a roller 20 carried on a lifting member 2|pivotally mounted at 22 on a bracket 23 secured to the tractor body nearthe front end thereof. The under side of the front of the thresher partl8 carries brackets 24 (only one being shown) supporting rollers 25(only one being shown) resting in lifting members 26 (only one beingshown) secured to a sleeve 26 mounted upon the left-hand rear axle I5.The harvester part I9 is pivotally connected to the thresher part I 8 onan axis represented by a shaft 21 at the front end of the thresher part|8 directly over the rear axle l5. A sprocket 21' mounted on the shaft21 drives a chain 26 which engages a pair of sprockets 29 carried on thethresher body. This structure forms a portion of a conventional drivefor the operating parts of the harvester thresher. Belt pulleys 39' and3| drive a belt 32 which also engages an idler sprocket 33'. Thisdriving construction also forms a part of the drive mechanism for thethresher part. The harvester part includes a reel 28, a reciprocatingcutter 29, an auger feed 39, and a canvas conveyor 3|. Said conveyordelivers the harvested crop upwardly and rearwardly and over thedrive-axle structure of the tractor, the portion of the crop-treating orthresher part l8 adjacent and above the driveaxle structure beingadapted to receive said crop. The tractor has a seat 32, a steeringwheel 33, and control members 34, all of which enable the tractor to berun rearwardly for the normal operation of the harvester-thresher l'l,which is gathering crops by the harvester part l9 and threshing them bythe thresher part |3.

When the harvester-thresher H is to be detached from the tractor ID, thelifting means fully shown and claimed in the copending application ofHitchcock et al., Serial No. 490,267, filed June 10, 1943, now PatentNo. 2,376,539 is employed. Before the harvester-thresher H is detached,an operation must be performed that forms one feature of the presentinvention. This operation is the moving of the harvester part so that itdoes not interfere with removal of the thresher part. In the embodimentillustrated this move ment consists of the raising of the harvester partl9 from the working position of Figure 4 in which it extends downwardlyand rearwardly from its pivot point on the thresher part l8 representedby the shaft 21 to the position of Figures 2 and 3, in which it extendsupwardly from a pivot on the shaft 21 sufliciently to clear the axle land the wheel H5 and all longitudinally aligned parts of the tractorbody. During normal operation of the harvester-thresher, the harvesterpart l9 may be adjusted in the position shown by a power member 35actuated by the usual power plant of the tractor l0, not shown, whichpower member acts through link 36, bell-crank 31, and link 38 upon theharvester part l9. When the harvester part I9 is to be raised, the link38 is disconnected therefrom, and the harvester part is lifted in anydesired manner to the position shown in Figure 3 in which it extendssomewhat upwardly from its pivot on the thresher part I8, and a portion39 thereof extending outwardly beyond the tractor wheel l6 is above thewheel |6 so as to clear it when the tractor I0 is backed away from thebarvester-thresher H. The harvester part I 9 is held in its raisedposition by a bail 40 connecting the harvester part I9 to the top of thefront end of the thresher part l8. Then a link 4| is connected with thepower member 35 and with a flange 42 secured to the mounting sleeve 26.A link 43 is connected to the power member 35 and to the lifting member2|. Then the harvester-thresher is lowered from the position of Figure 4to that of Figure 3 by the action of the power member 35. Feet 44support the harvester-thresher in the detached position of Figure 3.After the harvester-thresher I! has been detached, as shown in Figure 3,the tractor may be backed away from it. It will be noted that thethresher part I8 is so constructed and arranged with respect to thetractor that no part thereof overlies or underlies the tractor bodysufiiciently close thereto in a vertical direction to engage said bodyand thereby interfere with the necessary vertical movement of thethresher part during attaching the detaching. It will also be noted thatsaid thresher part is so constructed and arranged that no portionthereof extends laterally in such overlapping relation with respect tothe traction wheel at the harvester-thresher side of the tractor body asto engage and interfere with the longitudinal movement of the thresherpart relative to the tractor necessary for attaching and detaching. Forattachment of the harvesterthresher l! to the tractor 0, theaforementioned operations are reversed. The power member 35 acts to movethe lifting members 25 and 26 angularly to raise the harvester-thresherH to raised position. Then the bail 40 is disconnected, and theharvester part I9 is lowered from the raised position of Figures 2 and 3to the lowered working position of Figure 4.

Figure 5 shows the construction of Figure 4 which bears the samereference characters in so far as the same parts are shown. Figure 5 isadditionally broken away in section at the junction point of the pivotedharvester part |9 with the thresher part I 8 to show additionalstructure.

The thresher part I8 has the usual threshing cylinder 45 carried by ashaft 46. A portion of a concave 47 is also visible, said concaveunderlying the cylinder. An upper feed roll 48 cooperates with a lowerfeed roll 49 to feed material to the threshing cylinder. A deflectorplate 50 is shown underneath the feed roll 49 for assuring the deliveryof material between the threshing cylinder 45 and the concave 41. Anopening 5| is Drovided at the front portion of the thresher part Hi. Itwill be noted that said opening is above the tractor axle structurewhereby material may be delivered over said axle structure into thethresher mechanism.

The harvester part l9, in addition to the adjusting structure includingthe link 38 previously described, is pivotally carried on the shaft 21.Said shaft also provides a support for a rotatable member 53 whichcarries and drives the feed apron 3|. Said feed apron cooperates withthe bottom wall 54 of the harvester part to deliver harvested materialupwardly and rearwardly above the rear axle structure of the tractorinto the receiving opening 5| of the thresher part.

Figure 6 illustrates a modified means of removing the harvester from thetractor by first removing the harvester part |9 from the thresher partl8. Figure 6 shows the implement in its removed position from thetractor and supported by the feet at. The harvester part I9 is alsoshown as removed from the tractor, being supported by struts, one ofwhich, 55, is shown, and removable clamping means is illustratedincluding a swingable member 56 and a securing olement 51. The member 56is adapted to clamp over a portion of the shaft 52 for pivotallysecuring the harvester part E9 to the thresher part.

In removing the implement, as shown in the modification of Figure 6, theharvester part I9 is first removed and supported on the ground followingwhich the tractor is driven into a position where it can be driven inthe direction of the traction wheels away from the thresher part I8after said thresher part has been supported on the ground as shown inFigure 6.

It will be apparent from the foregoing description that there has beenprovided by the present invention a tractor-implement combination andalso means to perform an operation for facilitating removal of animplement such as a harvester-thresher from a tractor. This operationcomprises raising the harvester part of the harvester-threshersufficiently to clear the rear axle and wheel of the tractor so that,when the harvester-thresher is detached from the tractor, the tractormay be backed away from the harvester-thresher without interferencebetween the harvester part and the wheel and axle of the tractor. Theinvention has been illustrated as applied to a harvester-thresher, butit will be obvious that it may be applied to other types oftractor-mounted devices.

The intention is to limit the invention only within the scope of theappended claim.

What is claimed is:

A harvester thresher having a harvester part and a thresher part inwhich the thresher part includes a relatively long narrow high body and6 the harvester part is relatively wide, means pivotally connecting theharvester part to said thresher part near the top thereof, saidharvester thresher adapted to be mounted and removed from a standardtricycle type farm tractor having an axle normally disposed lower thansaid pivotal connection, means operatively connected to the thresherpart and the tractor for connecting the thresher part to the tractor formounting thereon, and removable connecting means carried on one of saidparts for joining the harvester part and thresher part in a manner inwhich the harvester part is swung upwardly about its pivotal connectionwhereby the harvester thresher may be mounted and removed from thetractor as a unit by driving the tractor with its axle under theharvester part without disassembling the harvester part from thethresher part because the wide harvester part is thus held in an upout-of-the-way position.
